Thermal wells are assigned for annealing of bars of high-alloy steels, providing the
elimination of internal tensions in a metal at a cast and cooling in moulds.
In accordance with a primary project thermal wells had the subhearch hearths and
special channels for recirculation of fuel burning products. In the process of exploitation of
wells unsatisfactory firmness of bottom, resulting in the protracted outages, related to repair
is educed. In this connection instead of the subhearch hearths with recirculation of products
of burning in the distance a 2000 mm from the level of bottom was set four burners of type
«pipe in a pipe». At a reconstruction looked the substantial change of character of heat
exchange in swept volume of well. It is set that at the increase of mass of load from 15 to
20-30 t and reduction of duration of outages of wells quality of heating of metal gets worse.
